Gets or sets an image this is displayed on this RibbonDropDownItem.
Assembly: Microsoft.Office.Tools.Common (in Microsoft.Office.Tools.Common.dll)
The recommended image format is PNG, because images in the PNG format support transparency through their alpha channel.
The property identifies an image that is displayed by the control. This property can be set at design time or at run time. If you update this property at run time, the control's appearance is updated to reflect the change.
If the property is set, the OfficeImageId property is ignored. Although the property gives you more control than the other two properties do, it can be slower because the image object is sent to the Office application every time the control is updated.
